Thanks for that and the site link. Very helpfully.

No worries about the plants I don't have any - cat eats them! so ain't have any.

We have open plan stairs and there isnt any carpet on them either so I dont think he will go upstairs, but I have a spare baby gate if he does end up there.
He will have our lounge and dinning room to run about in mainly, the kitchen and bathroom are off that so will only be there if kitchen door is open (cooker not in use when door open)
He will also have outside when I go out to see my other rabbits and our chickens - he's the only rabbit brave enough to go near the chickens when they are out of coop, not even the dog will lol

I'm really looking forward to having him indoors.
